Qin Tianchen saw Xu Shaolin and Sun Sisi's worries in his eyes, but he just smiled mysteriously, shook his head lightly, and didn't say anything.

Seeing Qin Tianchen's attitude, although the two of them were anxious, they couldn't say anything more.

After all, this formula was in Qin Tianchen's hands, and even Xu Shaolin didn't know it.

And most of the finished products in the laboratory have already been sealed, even if this princess really understands biology, it is impossible to deduce it in a short time.

What's more, the princess of the dignified empire is still obsessed with creatures, and this possibility is too low.

For a whole day, Diana stayed in the laboratory, and the accompanying Chinese officials were anxious.

They naturally also knew that in this laboratory, there were things comparable to national-level strategic materials, and if this princess of another country was allowed to grasp it, it would be a great disadvantage to Huaxia.

But after they asked the above, the above said that everything should be ordered by Mr. Qin.

This had to make them blind.

Because during this day, Qin Tianchen sat in the office and took a nap, Princess Diana didn't say that she wanted to leave, and he didn't bother to move.

What a reason for this!

If it weren't for the fact that this life spirit liquid was originally developed by Qin Tianchen, they would even think that Qin Tianchen was a spy of the British Empire!

It wasn't until the evening that Diana came over to find Qin Tianchen, looking a little tired.

"Qin, where am I staying tonight?"

As soon as she entered the office, Diana asked with a smile.

"Didn't the State Guesthouse arrange accommodation for you?" Qin Tianchen was stunned for a moment and asked.

"It's arranged, but I don't want to stay in the state guesthouse, I want to live with you, is it okay?" Diana looked at Qin Tianchen with a little hope in her eyes.

I have to say that if it weren't for Diana's skin, Qin Tianchen felt that he was going to be moved by her at this moment.

"That's right...... Then you can live in the villa, don't worry about safety, if you don't have enough conditions, you can't compare to the state guesthouse!" Qin Tianchen smiled, then got up and walked towards the door.

"It's okay! I'm not a delicate person!"

Looking at Qin Tianchen's back, Diana smiled, and her eyes flashed with unknown meaning.

Regarding Diana's small movements, Qin Tianchen watched the fire, but he didn't pay attention to it, just the corners of his mouth curled, and he left the office.

Diana hurried to follow.

Behind him, a group of staff members who had been idle for a day, as well as members of the visiting delegation, finally came to their senses and hurriedly followed behind.

After a while, the group of vehicles left Yenching University.

"Qin, aren't you afraid that I will deduce your Life Spirit Liquid formula and bring it back to my country?"

In the car, Diana squinted her eyes slightly, staring at Qin Tianchen's eyes carefully and asked.

Qin Tianchen raised his eyebrows and said with a smile: "It's okay, if you can deduce it from the finished product, others will naturally be able to, then won't I sell it to the outside world?"

Diana was stunned, then nodded with a smile: "That's right...... Qin is very confident!"

Qin Tianchen smiled and did not speak.

Diana, on the other hand, fell into deep thought, her eyes flashed with a little smugness, and the corners of her mouth couldn't help but curl slightly.

Of course, she knows that it is difficult to derive a recipe based on the finished product.

For the average biologist, it's almost an impossible task!

But she has faith!

As long as she was given enough time, she was confident that the recipe would no longer be a secret in her eyes.

If Qin Tianchen had always let her observe at will, she was confident that she would be able to deduce the formula within ten days.

The original expected duration was five days, so the visit was also scheduled for a week.

But now it seems that the country must be electrified and the visit extended for at least another week!

After returning to the villa, Qin Tianchen went upstairs alone and cultivated on the rooftop.

Diana was tired for a day, but she didn't bother him, ate some dinner from the state guesthouse, and then found a room to rest.

She suddenly did not live in the state guesthouse, but it was a burden for the entourage, who had to rearrange various security measures.

However, this is Qin Tianchen's villa, and there is a battalion of soldiers stationed on Yunwu Mountain, so the safety can be guaranteed, and they don't have a big fanfare.

After getting up early the next morning, Qin Tianchen had just gone downstairs, Diana was already ready to go, and the rest of the entourage were also looking at Qin Tianchen with blank eyes.

"Are you going to the lab today?" Qin Tianchen asked.

Diana smiled, nodded slightly, her eyes flowed, as if there was a flash of light, looking at Qin Tianchen with ripples.

Qin Tianchen shook his head, then cleaned up and went out.

Now Diana's wolf ambition has been revealed, and she doesn't even have any hidden meaning, she just came to run for the spiritual fluid of life.

Diana knew very well that even if she hid it well, Qin Tianchen would still find out.

The third strong man on the heavenly list, how can he hide it?

simply, she simply didn't bother to hide it, so she showed it bluntly.

In this way, Qin Tianchen is not easy to refuse, otherwise it will look dignified and Chinese, a big country, too stingy, isn't it?

Time passed silently.

For ten days in a row, Diana got up early every day, went straight to the laboratory, ate some work lunch at noon, and went back to Qin Tianchen's villa to rest at dusk.

And so on and so forth, day after day.

Qin Tianchen didn't say anything about Diana's extension of the visit to half a month, but Meng Lengqiu and them had a lot of complaints.

And Xu Shaolin and other personnel in charge of the life spirit liquid were so anxious that they couldn't sleep, and even had symptoms such as being unable to sleep and anorexia.

But Qin Tianchen still let Diana do whatever she wanted, except for the yeast that was hidden by Xu Shaolin, Diana studied everything else about the life spirit liquid.

At noon on the tenth day, in the laboratory.

Finally, Diana let out a long breath.

Sun Sisi happened to come in, ready to call the princess to dinner, and when she saw Diana's expression, her eyes couldn't help but change.

With a heartfelt thought, Sun Sisi did not ask Diana, but quietly left to find Qin Tianchen.

But as soon as she entered Qin Tianchen's office, Diana arrived on her hind feet.

"Qin, I want to ...... It's time for me to go home!"

Before anyone could enter, her voice entered the office.

Sun Sisi, who was reporting, hurriedly stopped, with an anxious look in his eyes, and motioned to Qin Tianchen.

Obviously, she wanted Qin Tianchen to keep Diana, and it was a while to be able to stay.

Combined with Diana's expression just now, and listening to the words at this moment, it is obvious that the formula of the life spirit liquid has been deduced by her!

At this time, if she was allowed to return to China, wouldn't she give something as important as the life spirit liquid to the British Empire?

How can this work! Sun Sisi embroidered his fists slightly, staring at Diana who broke into the office.
